Here’s my list of the 10 smallest frogs and toads in the world. I determined the order by the frog’s max size. This is what my research found but if you find a smaller one, don’t hesitate to holla at me.

At 10.9 mm, Paedophryne kathismaphlox is 10th smallest frog in the world.

Stumpffia yanniki measures in at 9.8 –10.6 mm, making it the 9th smallest frog

Gardiner’s frog (Sechellophryne gardineri) is only 10.1 mm long, make it the 8th smallest frog.

Monte Iberia eleuth (Eleutherodactylus iberia) maxes out at 10 mm. 7th smallest frog

Izecksohn’s toad (Brachycephalus didactylus) is only 9.8 mm long. It’s the 6th smallest frog
